Test programs
108
Various programs are available for monitoring cleaning performance
in routine testing. The test programs are not separate processing
programs. Rather, they are additional functions that can be activated
prior to starting any processing program.
The test programs interrupt the program cycle automatically at
specified points. The interruption is indicated by an audible signal
tone and message on the display. Miele Service can set the duration
of the interruption to between 10 seconds and approx. 42 minutes.
During this time period, measurements can be made or the door can
be opened to obtain a sample.
To prevent the wash cabinet from cooling, do not keep the door open
too long.
After the time period elapses, the program cycle continues
automatically. If the door has been opened, the program cannot
resume until the door has been closed again.
If a measurement or sample is not needed, you can resume the
program sooner by pressing the Start/Stop button.
The following test programs can be selected:
Laboratory
-
The program sequence can be paused in each wash block
immediately before the wash fluid is drained away.
Validation
-
The program sequence is interrupted at the following points:
– before the chamber washer solution is drained away in the final
wash block,
– after the interim rinse before the chamber washer solution is
drained away, and
– after water intake and before draining in the final rinse block.
